The Exar XRT7300IV is a versatile Line Interface Unit (LIU) designed for telecommunications applications requiring E3, DS3, or SONET STS-1 signaling. This single-chip solution integrates both the line transmitter and receiver, simplifying system design.
The XRT7300IV supports data rates of 34.368 Mbps for E3, 44.736 Mbps for DS3, and 51.84 Mbps for SONET STS-1. In the transmit direction, it encodes data into B3ZS or HDB3 formats and shapes the pulses for transmission over coaxial cable. The receive path includes equalization, clock recovery, data decoding, and line code violation detection.
Key features include compliance with E3/DS3/STS-1 jitter tolerance requirements, full loop-back capability, and power-down modes for efficient operation. The device operates from a single +5V power supply and is housed in a 44-pin TQFP package, suitable for surface mounting. Its operating temperature range is -40°C to +85°C.
This LIU is ideal for applications such as CSU/DSU equipment, PCM test equipment, fiber optic terminals, and multiplexers that interface with E3, DS3, or SONET STS-1 networks.
